Answer:
The maximum emf is 
The emf induced at t = 1.00 s is 
The maximum rate of change of magnetic flux is 
Explanation:
From the question we are told that
The number of turns is N = 44 turns
The length of the coil is 
The width of the coil is 
The magnetic field is 
The angular speed is 
Generally the induced emf is mathematically represented as

Where
is the maximum induced emf and this is mathematically represented as

Where
is the magnetic flux
N is the number of turns
A is the area of the coil which is mathematically evaluated as

Substituting values


substituting values into the equation for maximum induced emf


given that the time t = 1.0sec
substituting values into the equation for induced emf 


The maximum induced emf can also be represented mathematically as

Where
is the magnetic flux and
is the maximum rate at which magnetic flux changes the value of the maximum rate of change of magnetic flux is

Answer:
q = 0.036 C
Explanation:
Given that,
Current passes through a defibrillator, I = 18 A
Time, t = 2 ms
We need to find the charge moved during this time. We know that,
Electric current = charge/time

Put all the values,

So, 0.036 C of charge moves during this time.
Answer:
theory
Explanation:
that's why it's called the Big Bang Theory
Answer:
ratio =0.3075 T
Explanation:
The magnetic field B creates a force on a moving charge such that

Now this causes a centripetal acceleration

so
...........(i)
...............(ii)
If accelerating potential V is same and then kinetic energy equals the potential energy difference

put these value in equation (ii)
simplifying we get

for same location r will be same in both case
..............(iii)
..........(iv)
dividing (iv) and (iii) equation we get



so on solving we get
=0.3075 T
